Martha Jackson facilitated the acquisition of many important works though her New York gallery. After her death, her son and daughter-in-law gifted an additional 44 works from her remaining personal collection.

Upon her death in 2016, Marisol bequeathed her estate to the Albright-Knox, including more than 100 sculptures, more than 150 works on paper, thousands of photographs and slides, and a small group of works by other artists that she had collected.
